SPECIFICATION forming part of Letters Patent No. 758,921, dated May 3,1904.

Application filed September 4, 1903. Serial No. 171,913. (No model.)

To (b// 'll'lmn't i! may concern:

Be it known that l, AtnnNo (Juannns Jones, a subject of the Kingof GreatBritain, residing in the city of Newark, county of Essex, and State ofNewJersey, have invented a new and useful Stock-Guide, of which thefollowing is a specification.

This invention relates to stock-guides of an automatic class, and hasfor its objects to provide an automatically-adjustable guide, to set theguides at will either mechanically or by the stock, to insure the returnof the guide to its initial position after each passage of the stockbeyond it, to provide for the adjustment of a guide mechanism, and toproduce an inexpensive, durable, and etticient structure.

Referring to the drawings forming a part of this specification, Figure 1illustrates perspectively the improved guide mechanism in conjunctionwith a saw-table shown in parts. Fig. 2 is a plan view of the same,illustrating the parts displaced by the stock. Fig. 3 illustratesperspectively an auxiliary guide, and Fig. at is a transverse section ofthe same.

Similar characters of reference indicate like parts throughout thefigures.

A primary feature comprises a movable member 1, upon which is mounted astockguide 2, which in the present instance is initially in a positionnear a stock-working member such, for instance, as a circular saw 3.This movable member 1 is mounted preferably for reciprocation through abearing a, which is preferably fixed to a member 5, suitably extendingbeyond the bearing. as seen in Fig. 1. To or near the extremity of thisextended member 5 is attached by suitable means a resilient member 6,preferably attached to a head-piece T, secured to the extending member5. This resilient member is preferably in the form of a pressure-spring,whose free end is so connected withthe member 1 as to cause the latterto extend through the bearing *1 to an extreme position near the saw orworking member. In the present instance the resilient member simplybears against the extremity 9 of the member 1, which projects beyond theface of the bearing a, and this extended portion 9 may be threaded toreceive adjusting-nuts l0 and 11,

through the instrumentality of which the extent of projection of thestock-guide toward the working member may be determined.

For the purpose of arresting the stock-guide 2 in a predeterminedrelation to the working memberor in a predetermined position in the pathof movement thereof the rack-bar 12 is provided, which in the presentinstance is hinged, as at 13. to the bearing at, and may be providedwith a series of teeth 14 or their equivalent for engaging thestock-guide 2, which inthe present instance is chamfered or beveled atone end, as at l5, to fit in said teeth 14:, and this bar 12 is alsoprovided with an adjustment in the form of adjustingaiuts 16 and 17 oneach side of the hinged member 18, which carries the bar. Hence when themember-2 is adjusted by the nuts and 11 the bar 12 may becorrespondingly adjusted by nuts 16 and 17, so that the bar 12 ifgraduated to a scale may always be operative, even if the member 2 isadjusted to ditferentsettings that is to say, the scale, if such beused, may always be useful by the compound adjustment of the twomembers. This bar 12 is designed to be tripped by the stock, so thatwhen the latter is operated on by a stock-working member and has passedbeyond the face of a stockguide said guide may return to its initialposition. To this end the extremity 19 of the bar 12 extends beyond thesurface of the guide 2 and, as seen in Fig. 2, is tripped or forced backby the stock, whereupon the release of the guide is effected, and assoon as the stock passes beyond a predetermined point the guide, throughthe instrumentality of the resilient member 6, will fly back to itsinitial position. For the purpose of automatically returning the bar 12to its position against the end of the guide 2 I provide a resilientmember 21, which is affixed at one end to the bearing 4:, and the otherto the hinged member 18, which latter member the resilient memberactuates.

If desired, the saw-table 22 may be slotted, as at 23, so that theentire mechanism may be adjusted to and from the working member or saw,and for the purpose of fixing the bearing in a predetermined position onthe table any suitable device, such as screws 21 and 25, may

be employed. If desired, also, I may supply a set-screw 26 to arrest themember 2 in any position in the bearing, provided duplicate operationsof the Working member are desired.

It is sometimes desirable to cut the stock of varying dimensions in onedirection, but that the dimensions thereof in the transverse directionbe all the same. To this end I provide an auxiliary guide, which I placeto the saw 3 on a side opposite the automatic guide. This guidecomprises a plate 27,provided with slots 28. Secured thereto is avertical guide 29, Figs. 3 and 4:, upon which is mounted a sliding guide30, the guide-face 31 of which extends to the table 22. This guide isespecially adapted for cutting small stock. It will now be seen that ifthe automatic guide is used in connection with a circular saw, as shown,the stock may be cut in various Widths and thicknesses without thenecessity each time of resetting the guides, and that in the presentinstances the stock itself may be employed to force the guides back toa-predeterrnined and desirable point. It will be further noted thatunless the reverse is ordained by the setting of the guide in apredetermined position said guide after each passage therefrom of thestock will return to an initial position. It will be further noted thatthe entire guide mechanism may be adjusted at Will upon the table.

Within the purview of this invention I reserve the right to allmodifications of structure and operation, it being the primary design ofthis invention to provide an automatically-returnable stock-guide.

Having thus described my invention, I claim 1. In combination With a sawtable, of a stock-guide adjustable to and from the plane of the saw,means tending to shift the guide toward the saw, means to temporarilyhold the guide in any position, said means engageable by the Work by itspassage past the saw to disengage the guide to let it return to the saw.

2. A stock-guide comprising a reciprocatable guide,a bearing therefor, aresilient member adapted to press said guide automatically to an initialposition, a member connected to said bearing and adapted to hold saidguide in various predetermined positions With relation to the bearing,said member lying in the stockpath, and being releasable from the guideby the stock.

3. A stock-guide comprising a reciprocatable guide, a bearingtherefor,aresilient member adapted to press said guide automatically toan initial position, a member adapted to hold said guide in variouspredetermined positions with relation to the bearing, saidmember lyingin the stock-path, and being releasable from the guide by the stock.

4:. A stock-guide comprising a reciprocatable guide, a bearing therefor,resilient means connected to said guide and bearing and adapted toreturn said guide to an initial position after the passage of the stocktherefrom, a graduated member provided with devices for holding theguide in predetermined positions, said member lying in the stock-pathand being releasable from the guide by the stock, and means to returnsaid graduated member to its initial position.
